BACKGROUND ART

As a common household appliance, a heater is prevalent, however, ingeneral, the heater at present only has function for heating, so thatits practicability and cost performance have yet to be improved. Acommon method for realizing dynamical effect of real flames through redlight in the heater is to drive a fan with some laser paper-adheredstreamers thereon by a motor, and the fan float upwards the streamers togenerate ‘flame’ shaking effect when the fan rotates. However, theeffect is not vivid and ideal due to such flames just swinging, further,the swinging streamers under the rotation of the fan would generatenoises, disturbing the surroundings and users.

Therefore, a wide variety of heaters with humidifying functions appear,and reference is made to Chinese invention patent No. ZL02149256.5entitled “Intelligent Heat-Pipe Double-Phase Change Electric Heater”(authorized publication No. CN1223795C), the heater, comprising electricheating pipes, heat sinks, a water microparticle humidifier forhumidification, a negative ion generator for air purification and thelike, has the functions of adjusting indoor air temperature and humidityand purifying the air.

Similar reference can be made to CN2913908Y.

Further referring to Chinese invention patent No. ZL200720056152.9entitled “A Wall-mounted Humidification Electric Heater” (authorizedpublication No. CN201106923Y), it is composed of a shell, a water tank,an air pipe and a heating assembly, characterized in that an atomizingdevice connected to water outlets on the water tank is arranged at theside of the water tank, the output port of the atomizing device isconnected to the air pipe, a mist outlet nozzle is arranged on theoutput port of the air pipe, a mounted fixing clip is arranged at theback of the heater body. An object of humidification is realized by theatomizing device.

As an improvement, application No. 200710078328.5 of Chinese inventionpatent application entitled “Air Warmer With Humidifying Function”(publication No.: CN101029772A), in the application, ambient air drivenby a rotating wind wheel assembly flows through a heating element, partof heated air is released directly into the environment and part thereofflows to the water tank via a first air duct, the hot air with watervapor in the water tank flows to the air outlet of the warmer body froma second air duct, and is released into the environment for airhumidification, thus it is possible to keep humid in air while heating.

SUMMARY OF THE INVENTION

An object of the invention is to provide a simulation electric fireplacehaving simulation effect of flames, which can produce real smoke,provide humidification and heating functions while producing hot air toensure environment humidity. The electric fireplace is composed of threecomponents, 1. a heating assembly: composed of a heating coil or aninfrared heat pipe or a PTC heating body, and a fan. 2. flameeffect-creating assembly: composed of a light-reflecting brush rotatedby the motor, a light bulb (or LED light source), a simulation charcoal(or wood), and a plastic sheet flame screen. 3. mist-producing assembly:composed of an ultrasonic atomizer and a mist-blowing fan. Water isatomized by ultrasound waves into mist which is blown out from thecharcoal (or wood) by the mist-blowing fan. The blown mist is taken bythe heating fan for heating to produce hot air with certain humidity.Three functions, including simulation combustion, mist production, andair heating and humidification, are realized.

The technical solution to the technical problem of the present inventiondescribed above is that: an electronic ultrasonic generator atomizeswater to create smoke effect. Mist is taken into the heating device forheating and added into heated air, thereby ensuring certain humidity andtemperature of the air and making living environment more comfortable;simulation combustion effect is created at the same time, because themist leads to higher simulation of combustion. The present invention issuitable for all simulation fireplaces, including mobile, embedded, andwall-mounted ones.

Working principles of the invention: water is atomized with ultrasonicwaves produced by electronic vibration principle, the mist is blown outfrom the multiholes on the simulation charcoal by a mist blowing fan forsimulating the “smoke” produced by charcoal (or wood) combustion.

The “smoke” outlet is communicated with the air inlet of the hot airfan; the “smoke” is taken into the air fan and delivered into theheating body where it is heated to release into the air, therebygenerating air with certain humidity and temperature. The combustionsimulation device arranged in the shell is composed of a frame,simulation wood, a glass plate, a flame plate, and an electronic flamesource, wherein the frame in which the glass plate is arranged isarranged in the shell, the simulation wood is arranged in front of theglass plate, behind which a flame plate is arranged, a plurality offlame-shaped through holes are formed on the flame plate, it ischaracterized in that the electronic flame source is composed of asupport and a plurality of incandescent bulbs (or LED lamp bead rows)and a control circuit, the plurality of incandescent bulbs (or LED lampbead rows)are connected via wires and connected with the control circuitcomprising a remote control transmitter and a remote control receiver.

Preferably, the ultrasonic atomizer and the mist blowing fan blow outmist from the multiholes on the simulation charcoal to create smokeeffect. Simulation effect of the fireplace is thus more realistic.

Preferably, the present invention employs the ultrasonic principle forwater atomization, which brings in ornamental effect while conditioningair humidity and temperature for most comfortable living environment.

Compared with the prior art, advantages of the present invention arethat: the smoke effect of charcoal (or wood) combustion is created basedon the principle of ultrasonic atomization principle, achieving morevivid simulation effect. The mist is directly added into the air forconditioning the humidity and temperature to make the living environmentmore comfortable. The phenomenon that dewdrops are formed around thehumidifier during use is drastically avoided.

Three functions, including heating, humidification and ornamental use,are realized within one machine, and comprehensive energy consumptionrate is high; the humidifying device is optimized, and has smallinstallation volume and good security, and the air purification functionis realized through application of filters and germicidal lamps andphotocatalysts.
